The mesh radio channel can be set via the web interface using the “Mesh” tab on the
“Wireless Interfaces” page (see Figure 27).
7.2 ESSID
The ESSID, or Extended Service Set Identifier, is used in 802.11 communication to identify a
particular network. It differentiates logical networks that operate on the same radio channel.
The mesh radio ESSID for all the nodes in a mesh cluster must be the same. If you have
adjacent mesh clusters where one or more nodes from each cluster are within communication
range of each other, the ESSID for the clusters must be different.
The mesh radio ESSID is set as shown in the example below. The ESSID value must be a text
string that has a maximum length of 32 characters. It must only contain alphanumeric
characters, spaces, dashes (“-“), and underscores (“_”). The ESSID setting is case sensitive.
When setting an ESSID that contains spaces, the ESSID value must be enclosed by quotes.
The quotes are optional otherwise.
> use mesh0
mesh0> set essid=”enroute500_mesh”
The broadcast of the ESSID can be controlled with the ‘hide_essid’ parameter in the ‘mesh0’
interface. The example below shows how hiding of the ESSID can be enabled. You will
generally want the ESSID to be hidden, and it is hidden by default.
> use mesh0
mesh0> set hide_essid=yes
The mesh radio ESSID can be set via the web interface using the “Mesh” tab on the “Wireless
Interfaces” page (see Figure 27).
7.3 Encryption
The mesh radio link can be protected with an encryption key to prevent unauthorized users
from intercepting or spoofing mesh traffic. To enable encryption, set the ‘key’ parameter in the
‘mesh0’ interface. The ‘key’ parameter can either be specified as a 16-character ASCII string
preceded by “s:” or a 32-character hexadecimal string. Each node in a mesh cluster must have
the same encryption key. The examples below illustrate how to set the encryption key.
Encryption can be enabled using an ASCII key with
